The schema Active Directory pattern is applied as a collection of the types of objects stored in the directory. This is different from many catalogs that have schemas, where in their case the pattern is stored as a text file to read at startup. There are many advantages to storing patterns in the directory. For example, a user application can read

You may have heard or encountered something like this: A system administrator rookie accidentally entered "Chmod-r 777/" resulting in a huge tragedy, causing the entire system to be seriously damaged. In daily management, we have many tools that can be used to back up file permissions such as CP, rsync, Etckeeper, etc. If you use this backup tool, you really don't need to worry about changing file permissions.However, if you just want to temporarily back up the file permissions (not the file its
DNS viewsWhat are DNS Views (DNS view)?The DNS view is based on different customer sources (referred to as IP), and the DNS server uses different data files to complete the parsing process. In this process, the DNS server is the same, and the data files in the view are not the same. Therefore, different sources, using different data files to parse, so, the results will be resolved is not the same.Procedure for creating a DNS view1.

Because it is a 32-bit file system, the maximum capacity of the FAT32 partition is only 32TB, the volume of a single file cannot exceed 4GB, and the file name length can not excee
